By including the effect of fluid loading for the thin spherical shell in a
proper manner, so-called shell theories can predict the water-borne
pseudo-Stoneley waves described extensively in the literature. Shell theories
give reasonably good results for the motion of a bounded elastic shell by using
the assumption that various parts of the shell move together in some reasonable
manner. Without proper fluid loading, however, shell theories do not predict
the pseudo-Stoneley resonances observed in nature and predicted by exact
theory. With proper fluid loading, as well as rotary inertia and translational
and rotary kinetic energy terms, a shell theory can exactly predict these
water-borne resonances. These resonances are predicted by the shell theory and
compared with results from exact elastodynamical calculations. [Work supported
